WebFor this, we need to add one more process-block which performs following actions, Zero the timer : The value of the timer is set to zero, whenever the state of the system changes. Stop the timer : Value of the timer is incremented till the predefined ‘maximum value’ is reached and then it should be stopped incrementing.

Web08. jan 2024. · 1. The typical solution as used in some real-time systems, is to execute the state and then "burn" the remaining time after that, so that each state is always executed on fixed time intervals, with a given time slice.
